JOHN D. PEAOHEY, OF EAST ORANGE, NE'W JERSEY.

TELEPHONE ALARM SYSTEM.

SPECIFICATION forming part of Letters Patent No. 738,351, dated September 8, 1903. Application filed January 13, 1902. Serial No- 89,58 9, (N0 model.)

Be it known that I, JOHN D. PEACHEY, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Telephone Alarm Systems; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to certain improvements in that class of automatic fire-alarm' and telephone systems represented by that shown in my prior application, filed May 15, 1901, Serial No. 60,264, the objects of the present improvements being to simplify the matic fire-alarm attachments or appliances to be employed in connection with telephones as now commonly constructed and in use, to secure a more positive and certain transmission of the alarm, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved alarm and telephone apparatus and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure l is a diagrammatic plan of the device, showing the telephone and the alarm apparatus arranged adjacent thereto; and Fig. 2 is a detail showing a certain suspensory plate for normally holding a Weight attached to a certain telephone-rece'hcr or re ceiver-cord.

In said drawings, a indicates an ordinary telephone having the usual hook or lever Z), to which the receiver 0 is applied in opening the telephone-circuit.

01 indicates the electric wires with which the transmitter d and receiver a are connected, and 6 indicates a cord or other suitable connection, which extends from said receiver to a hell or alarm device f, arranged near the telephone and preferably in the same apartment or room therewith. Said cord or counection e is weighted and is thus adapted, when the Weight g is released, to draw the receiver c from its hook or lever h, and thus close the ordinary telephone-circuit, so that an alarm may be transmitted through the telephone-circuit d to the central office h of the telephone system. The relation of the Weighted cord and the support for the weight to the receiver and its hook or lever 19 is such that under normal conditions the said receiver and book can be used Without interfering with ordinary telephoning operations.

The bell device f comprises, preferably, .a

plate 2', fastened to or suspended from the wall or other suitable fixture of the apartment containing the telephone, and has an eye j, on which the cord or flexible connection 6 is looped or held. It has also a bell is, attached thereto in any suitable manner. ,Also on said plate are arranged an electromagnet Z and its armature m, so that when the bell-circuit n is closed and the magnet Z magnetized the armature m, connected with the hammer 0 of the bell, will be attracted and an alarm sounded upon said bell 7c. The saidbell-circuit a may be controlled bythe battery 1) and may be closed by a thermostat q or other circuit-closing device, so that should a burglar enter he will close the circuit or should a fire occur in the building the circuit will be closed and an alarm be sounded. The weight g is suspended from the laterallyextending post or arm 0", attached to the bellplate or support for the magnet, and adjacent to said post is arranged a pushing-rod 8, arranged in suitable hearings on said plate t' and extending from the armature m to the suspensory plate 1 attached to the weighted cord, so that when the armature m is attracted by the magnet it will move said pushrod longitudinally against the said suspensory plate 15 and throw said plate from its supporting post or arm. Thus the Weight will be free to fall and draw the cord or connection 6 with it, so that the said receiver 0 will be Withdrawn from the telephone hook or 1ever and by means well known close connection with the central oiiice. The attendant at the said central olrice will be able to hear the sounding of the bell is, and thus may call the attention of the fire-department or the police-station to the disturbance or con flagration indicated by the ringing of the bell.

Having/thus described the invention, what I claim as new is- 1. The combination with the telephone and its electric circuits and receiver, of an alarm device and its electric connections, a weight and its support arranged contiguous to said electric connections of the alarm device, said weight being adapted to be released from its support when the alarm connections are operated, a cord or connection between said weight and receiver, and means governed by said alarm device for disengaging the weight from its said support causing the said weight to draw the receiver from the telephone and operate the telephone-circuit, substantially as set forth.

2. The combination with atelephone,and its electrical circuits, connecting with a central office, and a receiver-arm adapted to close the said circuit upon the withdrawal of the receiver, of said receiver and a weight adapted to withdraw said receiver from said receiver-arm, an alarm-bell and its electrical connections and means governed by said electrical connections for normally preventing said weight from acting upon said receiver, substantially as set forth.

3. The combination with the telephone and the telephone-receiver, of a connection 6, attached to said receiver, a weight attached to said connections and adapted to be normally supported near the said telephone, means for normally supporting said weight and an electrical alarm and releasing device electrically separate from the telephone adapted to simultaneously sound an audible alarm and release the weight whereby the said receiver is drawn away from the telephone and the latter rendered capable of transmitting the audible alarm, substantially as set forth.

4. The combination with the telephone, its electric circuit, and receiver adapted to hold said circuit open, of a weight connected to said receiver and adapted to draw said re: ceiver away from said telephone to permit a closing of said circuit, means separate from the telephone for supporting said weight and means for releasing the weight from its support and sounding an alarm, substantially as set forth.

5. In combination with the plate having a hook or eyej, a supporting-arm r, and a pushrod, of an electromagnet an armature adapted to engage said push-rod, a Weighted connection connected with a receiver and adapted to be caught by said arm and tobe pushed therefrom by said push-rod when the latter is acted upon by the said armature, substantially as set forth.

6. The combination with a plate having alarm-sounding means thereon, an eye or hook to support a cord and an arm or post to support a weight, of said weight, a push-rod to release the said weight from the said arm or post, and electromagnetic means for simultaneously sounding an alarm and operating said push-rod, substantially as set forth.

7. In combination with a plate having alarm-sounding means thereon, a support for a weight and electromagnetic means for simultaneously producing an audible alarm on said sounding means and releasing said weightfrom its support, said weight, and a telephonic receiver in connection with said weight and adapted to be operated to effect a closing of the telephone-circuit and said telephone and its electric circuit and connections, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 30th day of December, 1901.

JOHN D. PEACHEY.
